This set of water pump pliers have a push button for quick and easy adjustments and simple release. They have adjustable jaws that can accommodate a variety of object sizes. The induction hardened, serrated teeth and diamond-shaped jaws enhance both torque and grip on round, flat, square, and hex shapes. The head is finely ground and finished with black oxide and electrophoretic plating, which provides superior corrosion resistance. Additionally, the ergonomic soft grip handles ensure a secure and comfortable hold, helping to reduce effort and fatigue during use.
